New Cars for 2013: Porsche

Charting the changes for the 2013.

Cayenne (shown above): Now it's really a truck: A new diesel Cayenne gets compression-ignition grunt from a 240-hp, 3.0-liter V-6 feeding 406 pound-feet of torque through an eight-speed automatic transmission and standard all-wheel drive. Much lower on the blasphemeter, a new GTS model fits between the S and the Turbo, bearing a 420-hp version of the S's V-8. It stands 0.8 inch lower than the S and borrows the Turbo's wide-mouth front-end treatment.

Cayman: The next-gen Cayman will join its redone Boxster sibling later in 2013. The coupe will again have a slight power advantage over the Boxster.

Panamera: Like the Cayenne, the Panamera line also adds a GTS variant, bridging the gap between the 4S and Turbo sedans. It mixes a higher-output version of the S's V-8 (430 horsepower versus 400) with all-wheel drive and the Turbo's wheels, brakes, and three-piece spoiler. Twenty-inch wheels with all-season rubber are now an option.

911: The all-wheel-drive Carrera 4 and 4S transition to the type-991 platform this model year. Active cruise control joins the options list for the new coupes and convertibles. The 997 platform continues in Turbo and Turbo S trim.
